I tried a cubic curve and it does look better. I agree that the "broken" may
caused by the data points.
Thanks a lot for your help :)

It is a pleasure. :-D
I have posted a couple of screenshots in p.b.images along with the lathe
code I modified, a bit. As an example to show what I did.

For a quadratic_spline, the FIRST point is a controll point, all others
are actual points that are actualy used and, also, serve as controll
points for the next point but not for the previous one. The curve is
controlled from the second to third point but not from the third to
second points.
In most cases, using the cubic_spline gives beter results.
In your case, it will shorten the object by one interval.
In some cases, using less points can help.

If I remember correctly. Bishop3D's trial allows you to save scenes with
up to 4 objects. That would allow you to work on a lathe and save it.
You would need to install PovRay 3.6 to get an immage but you can
inspect the code and copy and past into your 3.7 scene.

Use version 3.7. Version 3.6.x is obsolete.
Next, it's just a mather of refering the correct path.

How interesting I thought it had to do with the Comm.dll not being
updated for 64 bit. At least that is what Hugo told me. It might run on
a 32 bit machine. I have no way of knowing.

For POV-Ray: The installer for version 3.7 will install the 32 bits
version on a 32 bits system and the 64 bits version on a 64 bits system.
For Bishop3D, even if it's a 32 bits application, it should be able to
run on a 64 bits system, in 32 bits compatibility mode.

PovRay installed pvengine, pvengine32-sse2 and pvengine64 on my machine.
Bishop3D will run pvengine & pvengine32-sse2 quite happily. It has been
a long time since I checked.
It will start pvengine64 but not render any files. PovRay stops after
the list of contributors.
So it will run PovRay 3.7 but not as a 64 bit application.

Thanks a lot! That's really helpful.
